Supplements may be helpful for leaky gut and one of our favorite gut support products is the amino acid, l-glutamine. Plus, there are so many additional advantages of l-glutamine for the gut to benefit from.

What Is Leaky Gut?

As food enters the intestines, it's broken down into individual nutrients that can pass through the tight junctions of the intestinal lining and into the bloodstream to be used in the rest of the body. The gut lining keeps large particles, bacteria, and toxins from passing through in the same way that nutrients do. These undesirable particles are swept out of the body with other waste. However, with leaky gut the intestinal lining is not as robust and allows these particles and toxins through the intestinal wall and into the bloodstream, and this can wreak havoc on the body.

Symptoms of Leaky Gut

Leaky gut leads to more than just stomach pain. Symptoms of leaky gut are often quite different from person to person. These symptoms may indicate that an individual’s intestinal lining isn’t working correctly: fatigue, food allergies/Sensitivities (especially gluten and dairy), post-nasal drip, headaches, skin conditions, constipation, diarrhea, IBS, mood disorders, brain fog and thyroid disorders.

What Is L-Glutamine?

L-glutamine plays a vital role in a variety of processes. It especially helps in the case of leaky gut because it supports the body in restoring the intestinal lining, along with so many other benefits.

Supports Healthy Brain Function

Healthy brain requires a variety of vitamins and nutrients to maintain a fruitful mental state. Glutamine is one of those valuable amino acids for brain health. This is because glutamine makes up a large portion of the central nervous system. A lack of glutamine in the body can interrupt natural brain cycles and lead to numerous mood or nervous system disorders.

Supports a Healthy Digestive System

It is only natural that a condition known as “leaky gut” would cause problems in the digestive system and bowels. Gut-related issues seem to be more common than we think. One of the biggest concerns for digestive issues and bowel issues is inflammation. Fortunately, l-glutamine can support the body in lowering the inflammatory response in IBS and similar illnesses, according to a 2017 review.

Supports Healthy Food Choices

Due to its ability to support healthy blood glucose levels, l-glutamine supports healthy eating habits, instead of feeding cravings for sugars and carbohydrates that cause inflammation throughout the body (making leaky gut worse).

Supports Intestinal Health

Stomach ulcers and ulcerative colitis often accompany leaky gut as these conditions directly affect the intestines. L-glutamine has shown promising benefits in supporting the health of the intestines.


Taking l-glutamine as a supplement to complement a healthy diet can support your journey to a healthier gut. For some, acquiring enough l-glutamine through food may be easy. But, to get a consistent amount daily, supplementing may be a better route.
